Nursing Elites

1. A nurse is caring for a client who is receiving an epidural infusion for pain management. Which assessment finding requires immediate intervention from the nurse?

• A. Redness at the catheter insertion site
• B. Report of headache and stiff neck
• C. Temperature of 100.1 F (37.8 C)
• D. Pain rating of 8 on a scale of 0 to 10

Correct answer: B

Rationale:

2. A nurse in the medical-surgical unit has a newly admitted patient who is oliguric; the acute care nurse practitioner orders a fluid challenge of 100 to 200 mL of normal saline solution over 15 minutes. The nurse is aware this intervention will help:

• A. Distinguish hyponatremia from hypernatremia
• B. Evaluate pituitary gland function
• C. Distinguish reduced renal blood flow from decreased renal function
• D. Provide an effective treatment for hypertension-induced oliguria

Correct answer: C

Rationale: Administering a fluid challenge in oliguric patients helps to distinguish reduced renal blood flow from decreased renal function. This intervention aids in determining whether the oliguria is due to reduced renal blood flow (such as in fluid volume deficit or prerenal azotemia) or decreased renal function (such as in acute tubular necrosis). The response to this challenge can indicate the underlying cause. Choices A, B, and D are incorrect as they do not align with the purpose of a fluid challenge in oliguric patients.

3. Which electrolyte is important in the formation of the thyroid hormones?

• A. Sodium
• B. Iodine
• C. Iron
• D. Chloride

Correct answer: B

Rationale: Iodine is the correct answer because it is essential for the synthesis of thyroid hormones. The thyroid gland incorporates iodine into thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating metabolism, growth, and development. Sodium, iron, and chloride are not directly involved in the formation of thyroid hormones, making them incorrect choices.

4. You are the nurse caring for a patient who is to receive IV daunorubicin, a chemotherapeutic agent. You start the infusion and check the insertion site as per protocol. During your most recent check, you note that the IV has infiltrated so you stop the infusion. What is your main concern with this infiltration?

• A. Extravasation of the medication
• B. Discomfort to the patient
• C. Blanching at the site
• D. Hypersensitivity reaction to the medication

Correct answer: A

Rationale:

5. What is the main water-holding force in the blood capillaries?

• A. Capillary blood pressure
• B. Sodium in the blood plasma
• C. Protein in the blood plasma
• D. Chloride in the blood plasma

Correct answer: C

Rationale: The correct answer is C: Protein in the blood plasma. Plasma proteins, especially albumin, create oncotic pressure, which is the main force responsible for holding water within the blood capillaries. Capillary blood pressure (Choice A) is involved in pushing blood through the capillaries, while sodium and chloride in the blood plasma (Choices B and D) are electrolytes and do not play a significant role in the water-holding force within capillaries.
